Modern microwave ovens have all adopted impractical and quirky new UIs, when the old concept of knobs was simple and worked fairly well in the first place.
Since then I have made sure the microwave has two dials, one for time, one for effect.
Then came one with an option button for 80 or 100 degrees (176 or 212, in freedoms). Never knew I needed that, but that just changed my live and I can not do without it. Reason: 80 degrees water is hot enough for my needs and saves time.
Our latest has 3 buttons, with different possiblities, beebs like a maniac when ready (an option which is not unset-able) and can do things I never knew anyone would need (like keeping it at x degrees for y minutes).
I guess it is like evolution: you experiment, keep what works and get rid of all things unfit.
